BRAEDING-MACHINE.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed May 15, 1907. Serial No. 373,23.

To all whom it may concern:

Be it known that I, JACOB LUNDGREN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBraiding M achincs, of which the following is a specification.

This invention relates to that class of braid- '10 ing mai'whincswherein two sets of bobbins are employed, and each thread from one setof bobbins is passed entirely around two bobbins of the other set duringthe braiding operation, as illustrated in my application for patentSerial Number 179,807, filed Novemher 4th, 1903, to which reference maybe had.

I The object of my present invention is to I produce a more simple andeilicient machine of this class. i

'llaving this'objcct in view, the invention consists in the novelconstruction and combi nations of arts hereinafter fully described andparticularly pointed out in the claims.

In the drawin: -l igure 1 is an elevation of a braiding machineembodying my invention. Fig. 2 is a sectional plan view thereof,enlarged, as seen from the line 2-2, of Fig. 1. Fig. 3 is a sectionalplan View, as on the line 3-3, of Fig. 1, certain parts being omitted.Fig. 4 is a vertical section as on the line ti""4, of Fig. 2. Fig. 5 isa sectional detail showing one of the upper bobbin carriers, andadjuncts, and the position of one of the upper bobbins with. respect tothe thread carrying arm l or one of the lower bobbins, when said. armpasses said bobbin.

The main frame of the machine comprises the bed plate 6, and thestandards 7 and 8. Rising from the bed plate is a centrally arrangedtubular post 9, to which is fitted the hub 10 of a frame 11, so as to berotatable thereon.

Journaled in bearings 12 and 13 on the bed plate 6 is a driving shaft 14which is provided on its outer end with a suitable driving pulley 15,and on its inner end with a beveled gear wheel 16', in mesh with asimilar wheel 17 on. the hub 10 by means of which the frame 11 isrotated. Arranged around the 59 frame 11 and secured thereto, areupwardly projecting shafts 18. The upper ends of the shafts 18 supporthorizontally arranged plates 19 which extend toi'ard each other,

and terminate before meeting each other,

55 therebyleaviug open spaces bctween'thcir opposite ends, Arrangeddirectly below the vertical spaces between plates 19 and? Extendingthrough the spaces laetweentimplates 19 and 20, and fitted to thetrac'ku ways 22, are sector-like carriers 23, adapted to travel aroundsaid tracl ways, the length of the carriers 23 being much greater thanthe distance between the adjacent ends of the plates .19 and theadjacent ends of the plates 20. The peripheries of the carriers 23 areprovided with gear teeth, adapted to be engaged by the teeth of pinions24, which are rotatably mounted on the shafts 21, and arranged betweenthe plates 19 and 20. These pinions 24 are so placed and arranged withrelation to each other and to the trackways 22, that during the rotationof said pinions, the carriers 23 willbe rotated about the tracirways 22,and that before the teeth of the carriers escape one pinion, said teethwill be engaged with another pinion. The pinions 24 are driven by gearwheels 25 on the upper ends oi sleeves 26 which are rotatably mountedon. the shafts 18. The lower ends of the sleeves 26 are provided withgear wheels 27 in mesh with a fixed gear ring 28, which is supported onsuitable posts 29 rising irom the bed plate 6. Thus it will be seenthat, through the gear just described, during the rotation of the frame11, the carriers 23 will. be bodily rotated around the machine, and atthe same time, independn ently'rotated about their respective trackways.Extending upwardly from the car riers 23 through the spaces between theadjacent ends of the plates 19, are frames 30 carrying the upper set ofbobbins, 31. These frames 30 cariyposts 32, the upper ends of which areprovided with thread delivery eyes 33 which receive the threads 34 fromthe bobbins 3] and deliver them to the braiding point,

Mounted on brackets projecting-from the sleeves 26, are lower bobbins35; and fixed to the sleeves 26 are the angular thread guiding arms 36for the threads 37 from the lower bobbins along which the threads 37from the bobbins 31 are guided through suitable eyes,

plates 19 and 20, are circular grooves or as shown; The arm 56 providedwith a vertical portion which. clears the ends of the supergiiosedplates 1?) and 20, and passes through the spaces between the ends ofsaid plates and the next adjacent plates when the arm is rotated withits sleeve. Each arm 36 is also provided with a vertical portion 39which clears the two next adjacent bobbins 31 during the rotation. ofsaid arm. The free end of each arm 36 is provided with a threaddeliveryeye, 40, from which the threads 37 are delivered to the braiding point.During the operation. of each arm 36 about its own axis the verticalportion 39 thereof describes circle around the two adjacent bobbins 31,under which the arm passes. It follows, therefore, that the pathstraversed by the vertical portions 39 and the threads 37 carried therebyintersect each other and that two adjacent bobbins 31 are not onlyinclosed by the path traversed by one thread 37 but are also separatelyinclosed by the paths traversed by the threads 37 on the respectivethereof. The timing of the movement of the carriers 23 around theirtrack-ways with respect to the movement of the arms 36, is such thatwhen. a particular arm 36 is passing a particular bobbin 31, the carrierof the bobbin will over that portion of its trackwav w. ch is vnthmthepath traversed by the vertical portion 38 of the arm, and that the samecarrier, upon meeting the vertical portion. 38 of the next adjacent arm,will pass over that portion of its track-way which is withinthe pathtraversed by the vertical portion 38 of its next adjacent arm. Thus itwill beseen that each bobbin 31 is alternately sup'oorted within the twopaths traversed by t; e two adjacent rotatin arms 36,

in order to permit the passage of the threads 37 from the lower bobbinsentirely around the bobbins 31 and threads 34, delivered therefrom whichis one of the peculiar re quirements of a machine of this character.

The thrcads34 and 37 pass from the eyes 33 and 40 to the braiding point,which islocated at the lower end of a centrally arranged tube 41through. which the product of the machine passes, and which is supportedby an arm. 42 projected from a fixed shaft 43 which extends between theupper ends of the standards 7 and 8. I

The product of the machine passes up through the tube 41 and around asuitable take up wheel 44 which mounted loosely on the shaft 43. Thetake up wheel 44 is actuatedby a gear wheel 45, fixed to the sidethereof, and in mesh with a pinion 46 on a shaft 47, having its hearingsin the standards 7 and 8. ()no end of the shaft 47 extends outwardly andis provided with a gear wheel 4&8 in mesh with agear wheel 49 on one endof a SllQSf't shaft 56, mounted in a suitable bar iii. The other end ofthe shaft 50 is provided with a worm wheel 52 which is actuated by a Iworm on the upper end of a vertical shaft 54.

The lower end of the shaft 54 has fixed thereto a beveled gear wheel 55,which is driven by a similar wheel 56 on the main driving shaft 14, tothe end that when the main shaft 14 is actuated the take up wheel 44will be rotated.

By the above described construction, it will be seen that when power isapplied to the driving pulley 15, the rotation of the wheel 44 will drawthe threads through the eyes 33 and 40, from the bobbins 31 and 35respec tively, and up through the tube 41. During thisoperation, thethreads 34 from the bohbins 31 are being delivered direct to thebraiding point, and each thread 37 from the bobbins 35 is being guidedby its arm 36 entirely around two adjacent bobbins 31; the two bobbins31 that are inclosed by the path of one thread 37 being separatelyinclosed by the paths of the threads from the adjacent bobbins 35. Thusthe threads from the two sets of bobbins 31 and 35 are braided togetherupon meeting the braiding oint, to produce a cord, and said cord wil beprovided with a twist due to the bodily rotation of the bobbins 31 and35 around the machine during the braiding operation.
